FIELD

Provided herein are methods, compounds, and compositions for reducing expression of DMPK mRNA and protein in an animal. Also, provided herein are methods, compounds, and compositions comprising a DMPK inhibitor for preferentially reducing CUGexp DMPK RNA, reducing myotonia, or reducing spliceopathy in an animal. Such methods, compounds, and compositions are useful, for example, to treat, prevent, or ameliorate type 1 myotonic dystrophy (DM1) in an animal.

BACKGROUND

Myotonic dystrophy type 1 (DM1) is the most common form of muscular dystrophy in adults with an estimated frequency of 1 in 7,500 (Harper P S., Myotonic Dystrophy. London: W.B. Saunders Company; 2001). DM1 is an autosomal dominant disorder caused by expansion of a non-coding CTG repeat in DMPK1. DMPK1 is a gene encoding a cytosolic serine/threonine kinase (Brook J D, et al., Cell., 1992, 68(4):799-808). The physiologic functions and substrates of this kinase have not been fully determined. The expanded CTG repeat is located in the 3′ untranslated region (UTR) of DMPK1. This mutation leads to RNA dominance, a process in which expression of RNA containing an expanded CUG repeat (CUGexp) induces cell dysfunction (Osborne R J and Thornton C A., Human Molecular Genetics., 2006, 15(2): R162-R169).

The DMPK gene normally has 5-37 CTG repeats in the 3′ untranslated region. In myotonic dystrophy type I, this number is significantly expanded and is, for example, in the range of 50 to greater than 3,500 (Harper, Myotonic Dystrophy (Saunders, London, ed. 3, 2001); Annu. Rev. Neurosci. 29: 259, 2006; EMBO J. 19: 4439, 2000; Curr Opin Neurol. 20: 572, 2007).

The CUGexp tract interacts with RNA binding proteins including muscleblind-like (MBNL) protein, a splicing factor, and causes the mutant transcript to be retained in nuclear foci. The toxicity of this RNA stems from sequestration of RNA binding proteins and activation of signaling pathways. Studies in animal models have shown that phenotypes of DM1 can be reversed if toxicity of CUGexp RNA is reduced (Wheeler T M, et al., Science., 2009, 325(5938):336-339; Mulders S A, et al., Proc Natl Acad Sci USA., 2009, 106(33):13915-13920).

In DM1, skeletal muscle is the most severely affected tissue, but the disease also has important effects on cardiac and smooth muscle, ocular lens, and brain. The cranial, distal limb, and diaphragm muscles are preferentially affected. Manual dexterity is compromised early, which causes several decades of severe disability. The median age at death is 55 years, usually from respiratory failure (de Die-Smulders C E, et al., Brain., 1998, 121(Pt 8):1557-1563).

Antisense technology is emerging as an effective means for modulating expression of certain gene products and may therefore prove to be uniquely useful in a number of therapeutic, diagnostic, and research applications for the modulation of DMPK1. Intramuscular injection of fully modified oligonucleotides targeting with the CAG-repeat were shown in mice to block formation of CUGexp-MBNL1 complexes, disperse nuclear foci of CUGexp transcripts, enhance the nucleocytoplasmic transport and translation of CUGexp transcripts, release MBNL proteins to the nucleoplasm, normalize alternative splicing of MBNL-dependent exons, and eliminate myotonia in CUGexp-expressing transgenic mice (Wheeler T M, et al., Science., 2009, 325(5938):336-339; WO2008/036406).

Presently there is no treatment that can modify the course of DM1. The burden of disease, therefore, is significant. It is, therefore, an object herein to provide compounds, compositions, and methods for treating DM1

SUMMARY

Provided herein are methods, compounds, and compositions for inhibiting expression of DMPK and treating, preventing, delaying or ameliorating a DMPK related disease and or a symptom thereof. In certain embodiments, the compounds and compositions disclosed herein inhibit mutant DMPK or CUGexp DMPK.

Certain embodiments provide a method of reducing DMPK expression in an animal comprising administering to the animal a compound comprising a modified oligonucleotide as further described herein targeted to DMPK.

Certain embodiments provide a method of preferentially reducing CUGexp DMPK relative to wild-type DMPK, reducing myotonia, or reducing spliceopathy in an animal comprising administering to the animal a compound comprising a modified oligonucleotide, as further described herein, targeted to CUGexp DMPK. In certain instances, CUGexp DMPK transcripts are believed to be particularly sensitive to antisense knockdown via nuclear ribonucleases (such as RNase H), because of their longer residence time in the nucleus, and this sensitivity is thought to permit effective antisense inhibition of CUGexp DMPK transcripts in relevant tissues such as muscle despite the biodistribution barriers to tissue uptake of antisense oligonucleotides. Antisense mechanisms that do not elicit cleavage via nuclear ribonucleases, such as the CAG-repeat ASOs described in, for example, Wheeler T M, et al., Science., 2009, 325(5938):336-339 and WO2008/036406, do not provide the same therapeutic advantage.

Certain embodiments provide a method of treating an animal having type 1 myotonic dystrophy. In certain embodiments, the method includes administering to the animal a therapeutically effective amount of a compound comprising a modified oligonucleotide as further described herein targeted to DMPK. In certain embodiments, the method includes identifying an animal with type 1 myotonic dystrophy.

Certain embodiments provide a method of treating, preventing, delaying, or ameliorating symptoms and outcomes associated with development of DM1 including muscle stiffness, myotonia, disabling distal weakness, weakness in face and jaw muscles, difficulty in swallowing, drooping of the eyelids (ptosis), weakness of neck muscles, weakness in arm and leg muscles, persistent muscle pain, hypersomnia, muscle wasting, dysphagia, respiratory insufficiency, irregular heartbeat, heart muscle damage, apathy, insulin resistance, and cataracts. Certain embodiments provide a method of treating, preventing, delaying, or ameliorating symptoms and outcomes associated with development of DM1 in children, including, developmental delays, learning problems, language and speech issues, and personality development issues.

Certain embodiments provide a method of administering an antisense oligonucleotide to counteract RNA dominance by directing the cleavage of pathogenic transcripts.

Antisense Compounds

Oligomeric compounds include, but are not limited to, oligonucleotides, oligonucleosides, oligonucleotide analogs, oligonucleotide mimetics, antisense compounds, antisense oligonucleotides, and siRNAs. An oligomeric compound can be “antisense” to a target nucleic acid, meaning that is capable of undergoing hybridization to a target nucleic acid through hydrogen bonding.

In certain embodiments, an antisense compound has a nucleobase sequence that, when written in the 5′ to 3′ direction, comprises the reverse complement of the target segment of a target nucleic acid to which it is targeted. In certain such embodiments, an antisense oligonucleotide has a nucleobase sequence that, when written in the 5′ to 3′ direction, comprises the reverse complement of the target segment of a target nucleic acid to which it is targeted.

In certain embodiments, an antisense compound targeted to DMPK as described herein is 10 to 30 nucleotides in length. In other words, the antisense compounds are in some embodiments from 10 to 30 linked nucleobases. In other embodiments, the antisense compound comprises a modified oligonucleotide consisting of 8 to 80, 10 to 80, 12 to 30, 12 to 50, 15 to 30, 15 to 18, 15 to 17, 16 to 16, 18 to 24, 19 to 22, or 20 linked nucleobases. In certain such embodiments, the antisense compound comprises a modified oligonucleotide consisting of 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, or 80 linked nucleobases in length, or a range defined by any two of the above values. In certain embodiments, antisense compounds of any of these lengths contain at least 8, at least 9, at least 10, at least 11, at least 12, at least 13, at least 14, at least 15, at least 16, at least 17, at least 18, or at least 19, contiguous nucleobases of the nucleobase sequence of any of the exemplary antisense compounds described herein (e.g., at least 8 contiguous nucleobases of a nucleobase sequence recited in any one of SEQ ID NOs: 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, or 33-874.

In certain embodiments, the antisense compound comprises a shortened or truncated modified oligonucleotide. The shortened or truncated modified oligonucleotide can have a single nucleoside deleted from the 5′ end (5′ truncation), or alternatively from the 3′ end (3′ truncation). A shortened or truncated oligonucleotide can have two nucleosides deleted from the 5′ end, or alternatively can have two subunits deleted from the 3′ end. Alternatively, the deleted nucleosides can be dispersed throughout the modified oligonucleotide, for example, in an antisense compound having one nucleoside deleted from the 5′ end and one nucleoside deleted from the 3′ end.

When a single additional nucleoside is present in a lengthened oligonucleotide, the additional nucleoside can be located at the 5′ or 3′ end of the oligonucleotide. When two or more additional nucleosides are present, the added nucleosides can be adjacent to each other, for example, in an oligonucleotide having two nucleosides added to the 5′ end (5′ addition), or alternatively to the 3′ end (3′ addition), of the oligonucleotide. Alternatively, the added nucleoside can be dispersed throughout the antisense compound, for example, in an oligonucleotide having one nucleoside added to the 5′ end and one subunit added to the 3′ end.

It is possible to increase or decrease the length of an antisense compound, such as an antisense oligonucleotide, and/or introduce mismatch bases without eliminating activity. For example, in Woolf et al. (Proc. Natl. Acad. Sci. USA 89:7305-7309, 1992), a series of antisense oligonucleotides 13-25 nucleobases in length were tested for their ability to induce cleavage of a target RNA in an oocyte injection model. Antisense oligonucleotides 25 nucleobases in length with 8 or 11 mismatch bases near the ends of the antisense oligonucleotides were able to direct specific cleavage of the target mRNA, albeit to a lesser extent than the antisense oligonucleotides that contained no mismatches. Similarly, target specific cleavage was achieved using 13 nucleobase antisense oligonucleotides, including those with 1 or 3 mismatches.

Gautschi et al (J. Natl. Cancer Inst. 93:463-471, March 2001) demonstrated the ability of an oligonucleotide having 100% complementarity to the bcl-2 mRNA and having 3 mismatches to the bcl-xL mRNA to reduce the expression of both bcl-2 and bcl-xL in vitro and in vivo. Furthermore, this oligonucleotide demonstrated potent anti-tumor activity in vivo.

Maher and Dolnick (Nuc. Acid. Res. 16:3341-3358, 1988) tested a series of tandem 14 nucleobase antisense oligonucleotides, and a 28 and 42 nucleobase antisense oligonucleotides comprised of the sequence of two or three of the tandem antisense oligonucleotides, respectively, for their ability to arrest translation of human DHFR in a rabbit reticulocyte assay. Each of the three 14 nucleobase antisense oligonucleotides alone was able to inhibit translation, albeit at a more modest level than the 28 or 42 nucleobase antisense oligonucleotides.

It is understood that the sequence set forth in each SEQ ID NO in the Examples contained herein is independent of any modification to a sugar moiety, an internucleoside linkage, or a nucleobase. As such, antisense compounds defined by a SEQ ID NO can comprise, independently, one or more modifications to a sugar moiety, an internucleoside linkage, or a nucleobase. Antisense compounds described by Isis Number (Isis No) indicate a combination of nucleobase sequence and motif.

In certain embodiments, a target region is a structurally defined region of the target nucleic acid. For example, a target region can encompass a 3′ UTR, a 5′ UTR, an exon, an intron, an exon/intron junction, a coding region, a translation initiation region, translation termination region, or other defined nucleic acid region. The structurally defined regions for DMPK can be obtained by accession number from sequence databases such as NCBI and such information is incorporated herein by reference. In certain embodiments, a target region can encompass the sequence from a 5′ target site of one target segment within the target region to a 3′ target site of another target segment within the target region.

Targeting includes determination of at least one target segment to which an antisense compound hybridizes, such that a desired effect occurs. In certain embodiments, the desired effect is a reduction in mRNA target nucleic acid levels. In certain embodiments, the desired effect is reduction of levels of protein encoded by the target nucleic acid or a phenotypic change associated with the target nucleic acid.

A target region can contain one or more target segments. Multiple target segments within a target region can be overlapping. Alternatively, they can be non-overlapping. In certain embodiments, target segments within a target region are separated by no more than about 300 nucleotides. In certain embodiments, target segments within a target region are separated by a number of nucleotides that is, is about, is no more than, is no more than about, 250, 200, 150, 100, 90, 80, 70, 60, 50, 40, 30, 20, or 10 nucleotides on the target nucleic acid, or is a range defined by any two of the preceding values. In certain embodiments, target segments within a target region are separated by no more than, or no more than about, 5 nucleotides on the target nucleic acid. In certain embodiments, target segments are contiguous. Contemplated are target regions defined by a range having a starting nucleic acid that is any of the 5′ target sites or 3′ target sites listed herein.

Suitable target segments can be found within a 5′ UTR, a coding region, a 3′ UTR, an intron, an exon, or an exon/intron junction. Target segments containing a start codon or a stop codon are also suitable target segments. A suitable target segment can specifically exclude a certain structurally defined region such as the start codon or stop codon.

The determination of suitable target segments can include a comparison of the sequence of a target nucleic acid to other sequences throughout the genome. For example, the BLAST algorithm can be used to identify regions of similarity amongst different nucleic acids. This comparison can prevent the selection of antisense compound sequences that can hybridize in a non-specific manner to sequences other than a selected target nucleic acid (i.e., non-target or off-target sequences).

There can be variation in activity (e.g., as defined by percent reduction of target nucleic acid levels) of the antisense compounds within an active target region. In certain embodiments, reductions in DMPK mRNA levels are indicative of inhibition of DMPK protein expression. Reductions in levels of a DMPK protein are also indicative of inhibition of target mRNA expression. Further, phenotypic changes, such as a reducing myotonia or reducing spliceopathy, can be indicative of inhibition of DMPK mRNA and/or protein expression.

Hybridization

In some embodiments, hybridization occurs between an antisense compound disclosed herein and a DMPK nucleic acid. The most common mechanism of hybridization involves hydrogen bonding (e.g., Watson-Crick, Hoogsteen or reversed Hoogsteen hydrogen bonding) between complementary nucleobases of the nucleic acid molecules.

Hybridization can occur under varying conditions. Stringent conditions are sequence-dependent and are determined by the nature and composition of the nucleic acid molecules to be hybridized.

Methods of determining whether a sequence is specifically hybridizable to a target nucleic acid are well known in the art (Sambrooke and Russell, Molecular Cloning: A Laboratory Manual, 3^(rd) Ed., 2001). In certain embodiments, the antisense compounds provided herein are specifically hybridizable with a DMPK nucleic acid.

Complementarity

An antisense compound and a target nucleic acid are complementary to each other when a sufficient number of nucleobases of the antisense compound can hydrogen bond with the corresponding nucleobases of the target nucleic acid, such that a desired effect will occur (e.g., antisense inhibition of a target nucleic acid, such as a DMPK nucleic acid).

An antisense compound can hybridize over one or more segments of a DMPK nucleic acid such that intervening or adjacent segments are not involved in the hybridization event (e.g., a loop structure, mismatch or hairpin structure).

In certain embodiments, the antisense compounds provided herein, or a specified portion thereof, are, or are at least, 70%, 80%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% complementary to a DMPK nucleic acid, a target region, target segment, or specified portion thereof. In certain embodiments, the antisense compounds are at least 70%, at least 80%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, or 100% complementary to a DMPK nucleic acid, a target region, target segment, or specified portion thereof, and contain at least 8, at least 9, at least 10, at least 11, at least 12, at least 13, at least 14, at least 15, at least 16, at least 17, at least 18, or at least 19, contiguous nucleobases of the nucleobase sequence of any of the exemplary antisense compounds described herein (e.g., at least 8 contiguous nucleobases of a nucleobase sequence recited in any one of SEQ ID NOs: 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, or 33-874). Percent complementarity of an antisense compound with a target nucleic acid can be determined using routine methods, and is measured over the entirety of the antisense compound.

For example, an antisense compound in which 18 of 20 nucleobases of the antisense compound are complementary to a target region, and would therefore specifically hybridize, would represent 90 percent complementarity. In this example, the remaining noncomplementary nucleobases can be clustered or interspersed with complementary nucleobases and need not be contiguous to each other or to complementary nucleobases. As such, an antisense compound which is 18 nucleobases in length having 4 (four) noncomplementary nucleobases which are flanked by two regions of complete complementarity with the target nucleic acid would have 77.8% overall complementarity with the target nucleic acid and would thus fall within the scope of the present invention. Percent complementarity of an antisense compound with a region of a target nucleic acid can be determined routinely using BLAST programs (basic local alignment search tools) and PowerBLAST programs known in the art (Altschul et al., J. Mol. Biol., 1990, 215, 403 410; Zhang and Madden, Genome Res., 1997, 7, 649 656). Percent homology, sequence identity or complementarity, can be determined by, for example, the Gap program (Wisconsin Sequence Analysis Package, Version 8 for Unix, Genetics Computer Group, University Research Park, Madison Wis.), using default settings, which uses the algorithm of Smith and Waterman (Adv. Appl. Math., 1981, 2, 482 489).

In certain embodiments, the antisense compounds provided herein, or specified portions thereof, are fully complementary (i.e. 100% complementary) to a target nucleic acid, or specified portion thereof. For example, antisense compound can be fully complementary to a DMPK nucleic acid, or a target region, or a target segment or target sequence thereof. As used herein, “fully complementary” means each nucleobase of an antisense compound is capable of precise base pairing with the corresponding nucleobases of a target nucleic acid. For example, a 20 nucleobase antisense compound is fully complementary to a target sequence that is 400 nucleobases long, so long as there is a corresponding 20 nucleobase portion of the target nucleic acid that is fully complementary to the antisense compound. Fully complementary can also be used in reference to a specified portion of the first and/or the second nucleic acid. For example, a 20 nucleobase portion of a 30 nucleobase antisense compound can be “fully complementary” to a target sequence that is 400 nucleobases long. The 20 nucleobase portion of the 30 nucleobase oligonucleotide is fully complementary to the target sequence if the target sequence has a corresponding 20 nucleobase portion wherein each nucleobase is complementary to the 20 nucleobase portion of the antisense compound. At the same time, the entire 30 nucleobase antisense compound can be fully complementary to the target sequence, depending on whether the remaining 10 nucleobases of the antisense compound are also complementary to the target sequence.

The location of a non-complementary nucleobase can be at the 5′ end or 3′ end of the antisense compound. Alternatively, the non-complementary nucleobase or nucleobases can be at an internal position of the antisense compound. When two or more non-complementary nucleobases are present, they can be either contiguous (i.e. linked) or non-contiguous. In one embodiment, a non-complementary nucleobase is located in the wing segment of a gapmer antisense oligonucleotide.

In certain embodiments, antisense compounds that are, or are up to 10, 12, 13, 14, 15, 16, 17, 18, 19, or 20 nucleobases in length comprise no more than 4, no more than 3, no more than 2, or no more than 1 non-complementary nucleobase(s) relative to a target nucleic acid, such as a DMPK nucleic acid, or specified portion thereof.

In certain embodiments, antisense compounds that are, or are up to 10, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30 nucleobases in length comprise no more than 6, no more than 5, no more than 4, no more than 3, no more than 2, or no more than 1 non-complementary nucleobase(s) relative to a target nucleic acid, such as a DMPK nucleic acid, or specified portion thereof.

The antisense compounds provided herein also include those which are complementary to a portion of a target nucleic acid. As used herein, “portion” refers to a defined number of contiguous (i.e. linked) nucleobases within a region or segment of a target nucleic acid. A “portion” can also refer to a defined number of contiguous nucleobases of an antisense compound. In certain embodiments, the antisense compounds, are complementary to at least an 8 nucleobase portion of a target segment. In certain embodiments, the antisense compounds are complementary to at least a 10 nucleobase portion of a target segment. In certain embodiments, the antisense compounds are complementary to at least a 15 nucleobase portion of a target segment. Also contemplated are antisense compounds that are complementary to at least an 8, at least a 9, at least a 10, at least an 11, at least a 12, at least a 13, at least a 14, at least a 15, at least a 16, at least a 17, at least an 18, at least a 19, at least a 20, or more nucleobase portion of a target segment, or a range defined by any two of these values.

Identity

The antisense compounds provided herein can also have a defined percent identity to a particular nucleotide sequence, SEQ ID NO, or compound represented by a specific Isis number, or portion thereof. As used herein, an antisense compound is identical to the sequence disclosed herein if it has the same nucleobase pairing ability. For example, a RNA which contains uracil in place of thymidine in a disclosed DNA sequence would be considered identical to the DNA sequence since both uracil and thymidine pair with adenine. Shortened and lengthened versions of the antisense compounds described herein as well as compounds having non-identical bases relative to the antisense compounds provided herein also are contemplated. The non-identical bases can be adjacent to each other or dispersed throughout the antisense compound. Percent identity of an antisense compound is calculated according to the number of bases that have identical base pairing relative to the sequence to which it is being compared.

In certain embodiments, the antisense compounds, or portions thereof, are at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99% or 100% identical to one or more of the exemplary antisense compounds or SEQ ID NOs, or a portion thereof, disclosed herein.

Modifications

A nucleoside is a base-sugar combination. The nucleobase (also known as base) portion of the nucleoside is normally a heterocyclic base moiety. Nucleotides are nucleosides that further include a phosphate group covalently linked to the sugar portion of the nucleoside. For those nucleosides that include a pentofuranosyl sugar, the phosphate group can be linked to the 2′, 3′ or 5′ hydroxyl moiety of the sugar. Oligonucleotides are formed through the covalent linkage of adjacent nucleosides to one another, to form a linear polymeric oligonucleotide. Within the oligonucleotide structure, the phosphate groups are commonly referred to as forming the internucleoside linkages of the oligonucleotide.

Modifications to antisense compounds encompass substitutions or changes to internucleoside linkages, sugar moieties, or nucleobases. Modified antisense compounds are often preferred over native forms because of desirable properties such as, for example, enhanced cellular uptake, enhanced affinity for nucleic acid target, increased stability in the presence of nucleases, or increased inhibitory activity.

Chemically modified nucleosides can also be employed to increase the binding affinity of a shortened or truncated antisense oligonucleotide for its target nucleic acid. Consequently, comparable results can often be obtained with shorter antisense compounds that have such chemically modified nucleosides.

Modified Internucleoside Linkages

The naturally occurring internucleoside linkage of RNA and DNA is a 3′ to 5′ phosphodiester linkage. Antisense compounds having one or more modified, i.e. non-naturally occurring, internucleoside linkages are often selected over antisense compounds having naturally occurring internucleoside linkages because of desirable properties such as, for example, enhanced cellular uptake, enhanced affinity for target nucleic acids, and increased stability in the presence of nucleases.

Oligonucleotides having modified internucleoside linkages include internucleoside linkages that retain a phosphorus atom as well as internucleoside linkages that do not have a phosphorus atom. Representative phosphorus containing internucleoside linkages include, but are not limited to, phosphodiesters, phosphotriesters, methylphosphonates, phosphoramidate, and phosphorothioates. Methods of preparation of phosphorous-containing and non-phosphorous-containing linkages are well known.

In certain embodiments, antisense compounds targeted to a DMPK nucleic acid comprise one or more modified internucleoside linkages. In certain embodiments, the modified internucleoside linkages are phosphorothioate linkages. In certain embodiments, each internucleoside linkage of an antisense compound is a phosphorothioate internucleoside linkage.

Modified Sugar Moieties

Antisense compounds of the invention can optionally contain one or more nucleosides wherein the sugar group has been modified. Such sugar modified nucleosides may impart enhanced nuclease stability, increased binding affinity, or some other beneficial biological property to the antisense compounds. In certain embodiments, nucleosides comprise chemically modified ribofuranose ring moieties. Examples of chemically modified ribofuranose rings include without limitation, addition of substitutent groups (including 5′ and 2′ substituent groups, bridging of non-geminal ring atoms to form bicyclic nucleic acids (BNA), replacement of the ribosyl ring oxygen atom with S, N(R), or C(R₁)(R₂) (R, R₁ and R₂ are each independently H, C₁-C₁₂ alkyl or a protecting group) and combinations thereof. Examples of chemically modified sugars include 2′-F-5′-methyl substituted nucleoside (see PCT International Application WO 2008/101157 Published on Aug. 21, 2008 for other disclosed 5′,2′-bis substituted nucleosides) or replacement of the ribosyl ring oxygen atom with S with further substitution at the 2′-position (see published U.S. Patent Application US2005-0130923, published on Jun. 16, 2005) or alternatively 5′-substitution of a BNA (see PCT International Application WO 2007/134181 Published on Nov. 22, 2007 wherein LNA is substituted with for example a 5′-methyl or a 5′-vinyl group).

Examples of nucleosides having modified sugar moieties include without limitation nucleosides comprising 5′-vinyl, 5′-methyl (R or S), 4′-S, 2′-F, 2′-OCH₃, 2′-OCH₂CH₃, 2′-OCH₂CH₂F and 2′-O(CH₂)₂OCH₃ substituent groups. The substituent at the 2′ position can also be selected from allyl, amino, azido, thio, O-allyl, O—C₁-C₁₀ alkyl, OCF₃, OCH₂F, O(CH₂)₂SCH₃, O(CH₂)₂—O—N(R_(m))(R_(n)), O—CH₂—C(═O)—N(R_(m))(R_(n)), and O—CH₂—C(═O)—N(R_(l))—(CH₂)₂—N(R_(m))(R_(n)), where each R_(l), R_(m) and R_(n) is, independently, H or substituted or unsubstituted C₁-C₁₀ alkyl.

Examples of bicyclic nucleic acids (BNAs) include without limitation nucleosides comprising a bridge between the 4′ and the 2′ ribosyl ring atoms. In certain embodiments, antisense compounds provided herein include one or more BNA nucleosides wherein the bridge comprises one of the formulas: 4′-(CH₂)—O-2′ (LNA); 4′-(CH₂)—S-2; 4′-(CH₂)₂—O-2′ (ENA); 4′-CH(CH₃)—O-2′ and 4′-CH(CH₂OCH₃)—O-2′ (and analogs thereof see U.S. Pat. No. 7,399,845, issued on Jul. 15, 2008); 4′-C(CH₃)(CH₃)—O-2′ (and analogs thereof see PCT/US2008/068922 published as WO/2009/006478, published Jan. 8, 2009); 4′-CH₂—N(OCH₃)-2′ (and analogs thereof see PCT/US2008/064591 published as WO/2008/150729, published Dec. 11, 2008); 4′-CH₂—O—N(CH₃)-2′ (see published U.S. Patent Application US2004-0171570, published Sep. 2, 2004); 4′-CH₂—N(R)—O-2′, wherein R is H, C₁-C₁₂ alkyl, or a protecting group (see U.S. Pat. No. 7,427,672, issued on Sep. 23, 2008); 4′-CH₂—C(H)(CH₃)-2′ (see Chattopadhyaya et al., J. Org. Chem., 2009, 74, 118-134); and 4′-CH₂—C(═CH₂)-2′ (and analogs thereof see PCT/US2008/066154 published as WO 2008/154401, published on Dec. 8, 2008).

In nucleotides having modified sugar moieties, the nucleobase moieties (natural, modified or a combination thereof) are maintained for hybridization with an appropriate nucleic acid target.

In certain embodiments, antisense compounds targeted to a DMPK nucleic acid comprise one or more nucleotides having modified sugar moieties. In certain embodiments, the modified sugar moiety is 2′-MOE. In certain embodiments, the 2′-MOE modified nucleotides are arranged in a gapmer motif.

Modified Nucleobases

Nucleobase (or base) modifications or substitutions are structurally distinguishable from, yet functionally interchangeable with, naturally occurring or synthetic unmodified nucleobases. Both natural and modified nucleobases are capable of participating in hydrogen bonding. Such nucleobase modifications can impart nuclease stability, binding affinity or some other beneficial biological property to antisense compounds. Modified nucleobases include synthetic and natural nucleobases such as, for example, 5-methylcytosine (5-me-C). Certain nucleobase substitutions, including 5-methylcytosine substitutions, are particularly useful for increasing the binding affinity of an antisense compound for a target nucleic acid. For example, 5-methylcytosine substitutions have been shown to increase nucleic acid duplex stability by 0.6-1.2° C. (Sanghvi, Y. S., Crooke, S. T. and Lebleu, B., eds., Antisense Research and Applications, CRC Press, Boca Raton, 1993, pp. 276-278).

Additional unmodified nucleobases include 5-hydroxymethyl cytosine, xanthine, hypoxanthine, 2-aminoadenine, 6-methyl and other alkyl derivatives of adenine and guanine, 2-propyl and other alkyl derivatives of adenine and guanine, 2-thiouracil, 2-thiothymine and 2-thiocytosine, 5-halouracil and cytosine, 5-propynyl (—C≡C—CH₃) uracil and cytosine and other alkynyl derivatives of pyrimidine bases, 6-azo uracil, cytosine and thymine, 5-uracil (pseudouracil), 4-thiouracil, 8-halo, 8-amino, 8-thiol, 8-thioalkyl, 8-hydroxyl and other 8-substituted adenines and guanines, 5-halo particularly 5-bromo, 5-trifluoromethyl and other 5-substituted uracils and cytosines, 7-methylguanine and 7-methyladenine, 2-F-adenine, 2-amino-adenine, 8-azaguanine and 8-azaadenine, 7-deazaguanine and 7-deazaadenine and 3-deazaguanine and 3-deazaadenine.

Heterocyclic base moieties can also include those in which the purine or pyrimidine base is replaced with other heterocycles, for example 7-deaza-adenine, 7-deazaguanosine, 2-aminopyridine and 2-pyridone. Nucleobases that are particularly useful for increasing the binding affinity of antisense compounds include 5-substituted pyrimidines, 6-azapyrimidines and N-2, N-6 and 0-6 substituted purines, including 2 aminopropyladenine, 5-propynyluracil and 5-propynylcytosine.

In certain embodiments, antisense compounds targeted to a DMPK nucleic acid comprise one or more modified nucleobases. In certain embodiments, gap-widened antisense oligonucleotides targeted to a DMPK nucleic acid comprise one or more modified nucleobases. In certain embodiments, the modified nucleobase is 5-methylcytosine. In certain embodiments, each cytosine is a 5-methylcytosine.

Certain Antisense Compound Motifs

In certain embodiments, antisense compounds targeted to a DMPK nucleic acid have chemically modified subunits arranged in patterns, or motifs, to confer to the antisense compounds properties such as enhanced the inhibitory activity, increased binding affinity for a target nucleic acid, or resistance to degradation by in vivo nucleases.

Chimeric antisense compounds typically contain at least one region modified so as to confer increased resistance to nuclease degradation, increased cellular uptake, increased binding affinity for the target nucleic acid, and/or increased inhibitory activity. A second region of a chimeric antisense compound can optionally serve as a substrate for the cellular endonuclease RNase H, which cleaves the RNA strand of an RNA:DNA duplex.

Antisense compounds having a gapmer motif are considered chimeric antisense compounds. In a gapmer an internal region having a plurality of nucleotides that supports RNaseH cleavage is positioned between external regions having a plurality of nucleotides that are chemically distinct from the nucleosides of the internal region. In the case of an antisense oligonucleotide having a gapmer motif, the gap segment generally serves as the substrate for endonuclease cleavage, while the wing segments comprise modified nucleosides. In certain embodiments, the regions of a gapmer are differentiated by the types of sugar moieties comprising each distinct region. The types of sugar moieties that are used to differentiate the regions of a gapmer can in some embodiments include β-D-ribonucleosides, β-D-deoxyribonucleosides, 2′-modified nucleosides (such 2′-modified nucleosides can include 2′-MOE, and 2′-O—CH₃, among others), and bicyclic sugar modified nucleosides (such bicyclic sugar modified nucleosides can include those having a 4′-(CH₂)_(n)—O-2′ bridge, where n=1 or n=2). The wing-gap-wing motif is frequently described as “X—Y—Z”, where “X” represents the length of the 5′ wing region, “Y” represents the length of the gap region, and “Z” represents the length of the 3′ wing region. As used herein, a gapmer described as “X—Y—Z” has a configuration such that the gap segment is positioned immediately adjacent each of the 5′ wing segment and the 3′ wing segment. Thus, no intervening nucleotides exist between the 5′ wing segment and gap segment, or the gap segment and the 3′ wing segment. Any of the antisense compounds described herein can have a gapmer motif. In some embodiments, X and Z are the same, in other embodiments they are different. In a preferred embodiment, Y is between 8 and 15 nucleotides. X, Y or Z can be any of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 30 or more nucleotides. Thus, gapmers include, but are not limited to, for example 5-10-5, 4-8-4, 4-12-3, 4-12-4, 3-14-3, 2-β-5, 2-16-2, 1-18-1, 3-10-3, 2-10-2, 1-10-1, 2-8-2, 6-8-6, 5-8-5, 5-7-5, 1-8-1, or 2-6-2.

In certain embodiments, the antisense compound as a “wingmer” motif, having a wing-gap or gap-wing configuration, i.e. an X—Y or Y—Z configuration as described above for the gapmer configuration. Thus, wingmer configurations include, but are not limited to, for example 5-10, 8-4, 4-12, 12-4, 3-14, 16-2, 18-1, 10-3, 2-10, 1-10, 8-2, 2-13, or 5-13.

In certain embodiments, antisense compounds targeted to a DMPK nucleic acid possess a 5-10-5 gapmer motif. In certain embodiments, antisense compounds targeted to a DMPK nucleic acid possess a 5-7-5 gapmer motif. In certain embodiments, antisense compounds targeted to a DMPK nucleic acid possess a 3-10-3 gapmer motif. In certain embodiments, antisense compounds targeted to a DMPK nucleic acid possess a 4-8-4 gapmer motif.

Thus, an oligonucleotide may be described by its sugar modification motif, internucleoside linkage motif and/or nucleobase modification motif (as used herein, nucleobase modification motif describes the chemical modifications to the nucleobases independent of the sequence of nucleobases).

Certain Sugar Motifs

In certain embodiments, oligonucleotides comprise one or more type of modified sugar moieties and/or naturally occurring sugar moieties arranged along an oligonucleotide or region thereof in a defined pattern or sugar modification motif.

In certain embodiments, the oligonucleotides comprise or consist of a region having a gapmer sugar modification motif, which comprises two external regions or “wings” and an internal region or “gap.” The three regions of a gapmer motif (the 5′-wing, the gap, and the 3′-wing) form a contiguous sequence of nucleosides wherein at least some of the sugar moieties of the nucleosides of each of the wings differ from at least some of the sugar moieties of the nucleosides of the gap. Specifically, at least the sugar moieties of the nucleosides of each wing that are closest to the gap (the 3′-most nucleoside of the 5′-wing and the 5′-most nucleoside of the 3′-wing) differ from the sugar moiety of the neighboring gap nucleosides, thus defining the boundary between the wings and the gap. In certain embodiments, the sugar moieties within the gap are the same as one another. In certain embodiments, the gap includes one or more nucleoside having a sugar moiety that differs from the sugar moiety of one or more other nucleosides of the gap. In certain embodiments, the sugar modification motifs of the two wings are the same as one another (symmetric gapmer).

Compositions and Methods for Formulating Pharmaceutical Compositions

Antisense oligonucleotides can be admixed with pharmaceutically acceptable active or inert substance for the preparation of pharmaceutical compositions or formulations. Compositions and methods for the formulation of pharmaceutical compositions are dependent upon a number of criteria, including, but not limited to, route of administration, extent of disease, or dose to be administered.

Antisense compound targeted to a DMPK nucleic acid can be utilized in pharmaceutical compositions by combining the antisense compound with a suitable pharmaceutically acceptable diluent or carrier. A pharmaceutically acceptable diluent includes phosphate-buffered saline (PBS). PBS is a diluent suitable for use in compositions to be delivered parenterally. Accordingly, in one embodiment, employed in the methods described herein is a pharmaceutical composition comprising an antisense compound targeted to a DMPK nucleic acid and a pharmaceutically acceptable diluent. In certain embodiments, the pharmaceutically acceptable diluent is PBS. In certain embodiments, the antisense compound is an antisense oligonucleotide.

Pharmaceutical compositions comprising antisense compounds encompass any pharmaceutically acceptable salts, esters, or salts of such esters, or any other oligonucleotide which, upon administration to an animal, including a human, is capable of providing (directly or indirectly) the biologically active metabolite or residue thereof. Accordingly, for example, the disclosure is also drawn to pharmaceutically acceptable salts of antisense compounds, prodrugs, pharmaceutically acceptable salts of such prodrugs, and other bioequivalents. Suitable pharmaceutically acceptable salts include, but are not limited to, sodium and potassium salts.

A prodrug can include the incorporation of additional nucleosides at one or both ends of an antisense compound which are cleaved by endogenous nucleases within the body, to form the active antisense compound.

Another technique used to introduce antisense oligonucleotides into cultured cells includes electroporation.

Cells are treated with antisense oligonucleotides by routine methods. Cells are typically harvested 16-24 hours after antisense oligonucleotide treatment, at which time RNA or protein levels of target nucleic acids are measured by methods known in the art and described herein. In general, when treatments are performed in multiple replicates, the data are presented as the average of the replicate treatments.

The concentration of antisense oligonucleotide used varies from cell line to cell line. Methods to determine the optimal antisense oligonucleotide concentration for a particular cell line are well known in the art. Antisense oligonucleotides are typically used at concentrations ranging from 1 nM to 300 nM when transfected with LIPOFECTAMINE2000®, Lipofectin or Cytofectin. Antisense oligonucleotides are used at higher concentrations ranging from 625 to 20,000 nM when transfected using electroporation.

RNA Isolation

RNA analysis can be performed on total cellular RNA or poly(A)+mRNA. Methods of RNA isolation are well known in the art. RNA is prepared using methods well known in the art, for example, using the TRIZOL® Reagent (Invitrogen, Carlsbad, Calif.) according to the manufacturer's recommended protocols.

Analysis of Inhibition of Target Levels or Expression

Inhibition of levels or expression of a DMPK nucleic acid can be assayed in a variety of ways known in the art. For example, target nucleic acid levels can be quantitated by, e.g., Northern blot analysis, competitive polymerase chain reaction (PCR), or quantitaive real-time PCR. RNA analysis can be performed on total cellular RNA or poly(A)+mRNA. Methods of RNA isolation are well known in the art. Northern blot analysis is also routine in the art. Quantitative real-time PCR can be conveniently accomplished using the commercially available ABI PRISM® 7600, 7700, or 7900 Sequence Detection System, available from PE-Applied Biosystems, Foster City, Calif. and used according to manufacturer's instructions.

Quantitative Real-Time PCR Analysis of Target RNA Levels

Quantitation of target RNA levels can be accomplished by quantitative real-time PCR using the ABI PRISM® 7600, 7700, or 7900 Sequence Detection System (PE-Applied Biosystems, Foster City, Calif.) according to manufacturer's instructions. Methods of quantitative real-time PCR are well known in the art.

Prior to real-time PCR, the isolated RNA is subjected to a reverse transcriptase (RT) reaction, which produces complementary DNA (cDNA) that is then used as the substrate for the real-time PCR amplification. The RT and real-time PCR reactions are performed sequentially in the same sample well. RT and real-time PCR reagents are obtained from Invitrogen (Carlsbad, Calif.). RT, real-time-PCR reactions are carried out by methods well known to those skilled in the art.

Gene (or RNA) target quantities obtained by real time PCR are normalized using either the expression level of a gene whose expression is constant, such as cyclophilin A, or by quantifying total RNA using RIBOGREEN® (Invitrogen, Inc. Carlsbad, Calif.). Cyclophilin A expression is quantified by real time PCR, by being run simultaneously with the target, multiplexing, or separately. Total RNA is quantified using RIBOGREEN® RNA quantification reagent (Invitrogen, Inc. Eugene, Oreg.). Methods of RNA quantification by RIBOGREEN® are taught in Jones, L. J., et al, (Analytical Biochemistry, 1998, 265, 368-374). A CYTOFLUOR® 4000 instrument (PE Applied Biosystems) is used to measure RIBOGREEN® fluorescence.

Probes and primers are designed to hybridize to a DMPK nucleic acid. Methods for designing real-time PCR probes and primers are well known in the art, and can include the use of software such as PRIMER EXPRESS® Software (Applied Biosystems, Foster City, Calif.).

Analysis of Protein Levels

Antisense inhibition of DMPK nucleic acids can be assessed by measuring DMPK protein levels. Protein levels of DMPK can be evaluated or quantitated in a variety of ways well known in the art, such as immunoprecipitation, Western blot analysis (immunoblotting), enzyme-linked immunosorbent assay (ELISA), quantitative protein assays, protein activity assays (for example, caspase activity assays), immunohistochemistry, immunocytochemistry or fluorescence-activated cell sorting (FACS). Antibodies directed to a target can be identified and obtained from a variety of sources, such as the MSRS catalog of antibodies (Aerie Corporation, Birmingham, Mich.), or can be prepared via conventional monoclonal or polyclonal antibody generation methods well known in the art.

In Vivo Testing of Antisense Compounds

Antisense compounds, for example, antisense oligonucleotides, are tested in animals to assess their ability to inhibit expression of DMPK and produce phenotypic changes. Testing can be performed in normal animals, or in experimental disease models, for example, the HSA^(LR) mouse model of myotonic dystrophy (DM1).

The HSA^(LR) mouse model is an established model for DM1 (Mankodi, A. et al. Science. 289: 1769, 2000). The mice carry a human skeletal actin (hACTA1) transgene with 220 CTG repeats inserted in the 3′ UTR of the gene. The hACTA1-CUG^(exp) transcript accumulates in nuclear foci in skeletal muscles and results in myotonia similar to that in human DM1 (Mankodi, A. et al. Mol. Cell 10: 35, 2002; Lin, X. et al. Hum. Mol. Genet. 15: 2087, 2006). Hence, it is expected that amelioration of DM1 symptoms in the HSA^(LR) mouse by antisense inhibition of the hACTA1 transgene would predict amelioration of similar symptoms in human patients by antisense inhibition of the DMPK transcript.

Expression of CUG^(exp) RNA in mice causes extensive remodeling of the muscle transcriptome, much of which is reproduced by ablation of MBNL1. Hence, it is expected that normalization of the transcriptome in HSA^(LR) mice would predict normalization of the human transcriptome in DM1 patients by antisense inhibition of the DMPK transcript.

For administration to animals, antisense oligonucleotides are formulated in a pharmaceutically acceptable diluent, such as phosphate-buffered saline. Administration includes parenteral routes of administration. Following a period of treatment with antisense oligonucleotides, RNA is isolated from tissue and changes in DMPK nucleic acid expression are measured. Changes in DMPK protein levels are also measured.

Splicing

Myotonic dystrophy (DM1) is caused by CTG repeat expansions in the 3′ untranslated region of the DMPK gene (Brook, J. D. et al. Cell. 68: 799, 1992). This mutation leads to RNA dominance, a process in which expression of RNA containing an expanded CUG repeat (CUGexp) induces cell dysfunction (Osborne R J and Thornton C A., Human Molecular Genetics., 2006, 15(2): R162-R169). Such CUGexp are retained in the nuclear foci of skeletal muscles (Davis, B. M. et al. Proc. Natl. Acad. Sci. U.S.A. 94:7388, 1997). The accumulation of CUGexp in the nuclear foci leads to the sequestration of poly(CUG)-binding proteins, such as, Muscleblind-like 1 (MBLN1) (Miller, J. W. et al. EMBO J. 19: 4439, 2000). MBLN1 is a splicing factor and regulates the splicing of genes such as Serca1, CIC-1, Titin, and Zasp. Therefore, sequestration of MBLN1 by CUGexp triggers misregulated alternative splicing of the exons of genes that MBLN1 normally controls (Lin, X. et al. Hum. Mol. Genet. 15: 2087, 2006). Correction of alternative splicing in an animal displaying such disregulation, such as, for example, in a DM1 patient and the HSALR mouse model, is a useful indicator for the efficacy of a treatment, including treatment with an antisense oligonucleotide.

Certain Antisense Mechanisms

Myotonic dystrophy (DM1) is caused by CTG repeat expansions in the 3′ untranslated region of the DMPK gene. In certain embodiments, expansions in the 3′ untranslated region of the DMPK gene results in the transcription of RNA containing an expanded CUG repeat, and RNA containing an expanded CUG repeat (CUGexp) is retained in the nuclear foci of skeletal muscles. In certain instances, the cellular machinery responsible for exporting mRNA from the nucleus into the cytoplasm does not export RNA containing an expanded CUG repeat from the nucleus or does so less efficiently. In certain embodiments, cells do not export DMPK CUGexp mRNA from the nucleus or such export is reduced. Accordingly, in certain embodiments, DMPK CUGexp mRNA accumulates in the nucleus. In certain embodiments, more copies of DMPK CUGexp mRNA are present in the nucleus of a cell than are copies of wild-type DMPK mRNA, which is exported normally. In such embodiments, antisense compounds that reduce target in the nucleus will preferentially reduce mutant DMPK CUGexp mRNA relative to wild type DMPK mRNA, due to their relative abundences in the nucleus, even if the antisense compound does not otherwise distinguish between mutant and wild type. Since RNase H dependent antisense compounds are active in the nucleus, such compounds are particularly well suited for such use.

In certain instances, wild-type DMPK pre-mRNA and mutant CUGexp DMPK pre-mRNA are expected to be processed into mRNA at similar rate. Accordingly, approximately the same amount of wild-type DMPK pre-mRNA and mutant CUGexp DMPK pre-mRNA are expected to be present in the nucleus of a cell. However, after proceesing, wild type DMPK mRNA is exported from the nucleus relatively quickly, and mutant CUGexp DMPK mRNA is exported slowly or not at all. In certan such embodiments, mutant CUGexp DMPK mRNA accumulates in the nucleus in greater amounts than wild-type DMPK mRNA. In certain such embodiments, an antisense oligonucleotide targeted to the mRNA, will preferentially reduce the expression of the mutant CUGexp DMPK mRNA compared to the wild-type DMPK mRNA because more copies of the mutant CUGexp DMPK mRNA are present in the nucleus of the cell. In certain embodiments, antisense compounds targeted to pre-mRNA and not mRNA (e.g., targeting an intron) are not expected to preferentially reduce mutant DMPK relative to wild type, because the nuclear abundance of the two pre-mRNAs is likely to be similar. In certain embodiments, antisense compounds described herein are not targeted to introns of DMPK pre-mRNA. In certain embodiments, antisense compounds described herein are targeted to exons or exon-exon junctions present in DMPK mRNA. In certain embodiments, use of an antisense oligonucleotide to target the mRNA is therefore preferred because an antisense oligonucleotide having one or more features described herein (i) has activity in the nucleus of a cell and (2) will preferentially reduce mutant CUGexp DMPK mRNA compared to wild-type DMPK mRNA.

Certain Biomarkers

DM1 severity in mouse models is determined, at least in part, by the level of CUG^(exp) transcript accumulation in the nucleus or nuclear foci. A useful physiological marker for DM1 severity is the development of high-frequency runs of involuntary action potentials (myotonia).

ISIS 445569 is an appropriate representative comparator compound because ISIS 445569 demonstrates statistically significant reduction of human DMPK in vitro as measured using a plurality of primer probe sets (see e.g. Example 1 and Example 2 of WO 2012/012443). Additionally, ISIS 445569 demonstrates statistically significant dose-dependent inhibition of human DMPK in vitro in both human skeletal muscle cells and DM1 fibroblasts (see e.g. Example 4 and Example 5 of WO 2012/012443 and Example 28 of WO 2012/012467).

In some muscle tissues, for example, in the tibialis anterior, both ISIS 598768 and ISIS 598769 achieved greater inhibition of DMPK at 25, 50 and 100 mg/kg/wk than ISIS 445569 achieved at 200 mg/kg/wk. In the quadriceps and gastrocnemius, both ISIS 598768 and ISIS 598769 achieved equal or greater inhibition of DMPK at 50 mg/kg/wk than ISIS 445569 achieved at 100 or 200 mg/kg/wk. Thus, ISIS 598768 and ISIS 598769 have greater activity than ISIS 445569 at achieving dose-dependent inhibition of DMPK across multiple different muscle tissues.

In certain embodiments, the compounds disclosed herein are more tolerable than appropriate comparator compounds, such as ISIS 445569, when administered to CD-1 mice.

ISIS 598769, ISIS 598768, and ISIS 486178 were administered subcutaneously twice a week for 6 weeks at 50 mg/kg/wk. ISIS 445569 was administered subcutaneously twice a week for 6 weeks at 100 mg/kg/wk. After treatment, ALT, AST, and BUN levels were lower in ISIS 486178 and ISIS 598768 treated mice than in ISIS 445569 treated mice. After treatment, ALT and AST levels were lower in ISIS 598769 treated mice than in ISIS 445569 treated mice. Therefore, ISIS 598769, ISIS 598768, and ISIS 486178 are more tolerable than the comparator compound, ISIS 445569 in CD-1 mice.

In certain embodiments, the compounds disclosed herein are more tolerable than appropriate comparator compounds, such as ISIS 445569, when administered to Sprague-Dawley rats.

ISIS 598769, ISIS 598768, and ISIS 486178 were administered subcutaneously twice a week for 6 weeks at 50 mg/kg/wk. ISIS 445569 was administered subcutaneously twice a week for 6 weeks at 100 mg/kg/wk. After treatment, ALT and AST levels were lower in ISIS 486178, ISIS 598769, and ISIS 598768 treated mice than in ISIS 445569 treated mice. Therefore ISIS 598769, ISIS 598768, and ISIS 486178 are more tolerable than the comparator compound, ISIS 445569 in Sprague-Dawley rats.

In certain embodiments, elevated CK levels are associated with damage to cells in muscle tissue. In certain embodiments, elevated LDH levels are associated with cellular tissue damage.

In certain embodiments, the compounds disclosed herein are more tolerable than appropriate comparator compounds, such as ISIS 445569, when administered to cynomolgous monkeys. As provided in Example 19, groups of cynomolgous monkeys were treated with 40 mg/kg/wk of ISIS 598769, ISIS 598768, ISIS 486178, and ISIS 445569. Treatment with ISIS 445569 resulted in elevated ALT and AST levels at 93 days into treatment. Treatment with ISIS 598768, and ISIS 486178 resulted in lower ALT and AST levels at 58 and 93 days into treatment compared to ISIS 445569. Treatment with ISIS 598769, resulted in lower AST levels at 58 and 93 days into treatment and lower ALT levels at 93 days of treatment compared to ISIS 445569. Furthermore, the ALT and AST levels of monkeys receiving doses of ISIS 598769, ISIS 598768, and ISIS 486178 were consistent with the ALT and AST levels of monkeys given saline. Treatment with ISIS 445569 resulted in elevated LDH levels compared to the LDH levels measured in animals given ISIS 598769, ISIS 598768, and ISIS 486178 at 93 days into treatment. Additionally, treatment with ISIS 445569 resulted in elevated CK levels compared to the CK levels measured in animals given ISIS 598769, ISIS 598768, and ISIS 486178 at 93 days into treatment. Therefore, ISIS 598769, ISIS 598768, and ISIS 486178 are more tolerable than the comparator compound, ISIS 445569.

Example 2 Antisense Inhibition of Human DMPK in Human Skeletal Muscle Cells (hSKMc)

Antisense oligonucleotides targeted to a human DMPK nucleic acid were tested for their effect on DMPK RNA transcript in vitro. Cultured hSKMc cells at a density of 20,000 cells per well were transfected using electroporation with 10,000 nM antisense oligonucleotide. After approximately 24 hours, RNA was isolated from the cells and DMPK transcript levels were measured by quantitative real-time PCR. DMPK RNA transcript levels were adjusted according to total RNA content, as measured by RIBOGREEN®. Results are presented as percent expression of DMPK, relative to untreated control cells.

The antisense oligonucleotides in Tables 3, 4, 5, and 6 are 5-10-5 gapmers, where the gap segment comprises ten 2′-deoxynucleosides and each wing segment comprises five 2′-MOE nucleosides. The internucleoside linkages throughout each gapmer are phosphorothioate (P═S) linkages. All cytosine residues throughout each gapmer are 5-methylcytosines. ‘Target start site’ indicates the 5′-most nucleoside to which the antisense oligonucleotide is targeted in the human genomic gene sequence. ‘Target stop site’ indicates the 3′-most nucleoside to which the antisense oligonucleotide is targeted in the human genomic sequence. All the antisense oligonucleotides listed in Table 3, 4, or 5 target SEQ ID NO: 1 (GENBANK Accession No. NM_001081560.1). All the antisense oligonucleotides listed in Table 6 target SEQ ID NO: 2 (the complement of GENBANK Accession No. NT_011109.15 truncated from nucleotides 18540696 to Ser. No. 18/555,106).

Several of the antisense oligonucleotides in Tables 2, 3, 4, and 5 demonstrated significant inhibition of DMPK mRNA levels under the conditions specified above.

Example 3 Design of Antisense Oligonucleotides Targeting Human Dystrophia Myotonica Protein Kinase (hDMPK)

A series of antisense oligonucleotides (ASOs) were designed to target hDMPK. The newly designed ASOs were prepared using standard oligonucleotide synthesis well known in the art and are described in Table 7, below. Subscripts “s” indicate phosphorothioate internucleoside linkages; subscripts “k” indicate 6′-(S)—CH₃ bicyclic nucleosides (cEt); subscripts “e” indicate 2′-O-methoxyethyl (MOE) modified nucleosides; and subscripts “d” indicate β-D-2′-deoxyribonucleosides. “^(m)C” indicates 5-methylcytosine nucleosides.

The antisense oligonucleotides targeted to a human DMPK nucleic acid were tested for their effect on DMPK RNA transcript in vitro. Cultured HepG2 cells at a density of 20,000 cells per well were transfected using electroporation with 4,500 nM antisense oligonucleotide. After approximately 24 hours, RNA was isolated from the cells and DMPK transcript levels were measured by quantitative real-time PCR. DMPK RNA transcript levels were adjusted according to total RNA content, as measured by RIBOGREEN®. Results are presented as percent expression of DMPK, relative to untreated control cells. ‘Target start site’ indicates the 5′-most nucleoside to which the antisense oligonucleotide is targeted in the human genomic gene sequence. ‘Target stop site’ indicates the 3′-most nucleoside to which the antisense oligonucleotide is targeted in the human genomic sequence. All the antisense oligonucleotides listed in Table 7 target SEQ ID NO: 1 (GENBANK Accession No. NM_001081560.1).

Several of the antisense oligonucleotides demonstrated significant inhibition of DMPK mRNA levels under the conditions specified above.

Example 4 Design of Antisense Oligonucleotides Targeting Human Dystrophia Myotonica Protein Kinase (hDMPK) Dose Response HepG2

A series of antisense oligonucleotides (ASOs) were designed to target hDMPK. The newly designed ASOs were prepared using standard oligonucleotide synthesis well known in the art and are described in Table 8, below.

Example 8 ASOs Designed to Target a Human DMPK RNA Transcript

A series of antisense oligonucleotides (ASOs) were designed to target hDMPK. The newly designed ASOs were prepared using standard oligonucleotide synthesis well known in the art and are described in Table 12, below. Subscripts “s” indicate phosphorothioate internucleoside linkages; subscripts “k” indicate 6′-(S)—CH₃ bicyclic nucleosides (cEt); subscripts “e” indicate 2′-O-methoxyethyl (MOE) modified nucleosides; and subscripts “d” indicate β-D-2′-deoxyribonucleosides. “^(m)C” indicates 5-methylcytosine nucleosides.

The antisense oligonucleotides targeted to a human DMPK nucleic acid were tested for their effect on DMPK RNA transcript in vitro. Cultured hSKMC cells at a density of 20,000 cells per well were transfected using electroporation with 800 nM antisense oligonucleotide. After approximately 24 hours, RNA was isolated from the cells and DMPK transcript levels were measured by quantitative real-time PCR. DMPK RNA transcript levels were adjusted according to total RNA content, as measured by RIBOGREEN®. Results are presented as percent expression of DMPK, relative to untreated control cells.

‘Target start site’ indicates the 5′-most nucleoside to which the antisense oligonucleotide is targeted in the human genomic gene sequence. ‘Target stop site’ indicates the 3′-most nucleoside to which the antisense oligonucleotide is targeted in the human genomic sequence. All the antisense oligonucleotides listed in Table 12 target SEQ ID NO: 1 (GENBANK Accession No. NM_001081560.1).

Several of the antisense oligonucleotides demonstrated significant inhibition of DMPK mRNA levels under the conditions specified above.

Example 9 ASOs Designed to Target a Human DMPK RNA Transcript

A series of antisense oligonucleotides (ASOs) were designed to target hDMPK. The newly designed ASOs were prepared using standard oligonucleotide synthesis well known in the art and are described in Table 13 to 18, below. Subscripts “s” indicate phosphorothioate internucleoside linkages; subscripts “k” indicate 6′-(S)—CH₃ bicyclic nucleosides (cEt); subscripts “e” indicate 2′-O-methoxyethyl (MOE) modified nucleosides; and subscripts “d” indicate β-D-2′-deoxyribonucleosides. “^(m)C” indicates 5-methylcytosine nucleosides.

The antisense oligonucleotides targeted to a human DMPK nucleic acid were tested for their effect on DMPK RNA transcript in vitro. Cultured HepG2 cells at a density of 20,000 cells per well were transfected using electroporation with 4,500 nM antisense oligonucleotide. After approximately 24 hours, RNA was isolated from the cells and DMPK transcript levels were measured by quantitative real-time PCR. DMPK RNA transcript levels were adjusted according to total RNA content, as measured by RIBOGREEN®. Results are presented as percent expression of DMPK, relative to untreated control cells, with “% Target Expression” representing the percent expression of DMPK relative to untreated control cells

All the antisense oligonucleotides listed in Table 13 target SEQ ID NO: 1 (GENBANK Accession No. NM_001081560.1). All the antisense oligonucleotides listed in Table 14 to 18 target SEQ ID NO: 2 (the complement of GENBANK Accession No. NT_011109.15 truncated from nucleotide; 185406 to 18555106). ‘Target start site’ indicates the 5′-most nucleoside to which the antisense oligonucleotide is targeted in the human genomic gene sequence. ‘Target stop site’ indicates the 3′-most nucleoside to which the antisense oligonucleotide is targeted in the human genomic sequence.

Example 10 Dose Response Studies with Antisense Oligonucleotides Targeting Human Dystrophia Myotonica-Protein Kinase (DMPK) in HepG2 Cells

Antisense oligonucleotides targeted to a human DMPK nucleic acid were tested for their effect on human DMPK RNA transcript in vitro. Cultured HepG2 cells at a density of 20,000 cells per well were transfected using electroporation with 61.7 nM, 185.2 nM, 555.6 nM, 1666.7 nM, 5000.0 nM, and 15000.0 nM concentrations of each antisense oligonucleotide. After approximately 24 hours, RNA was isolated from the cells and DMPK RNA transcript levels were measured by quantitative real-time PCR using primer probe set RTS3164 (forward sequence AGCCTGAGCCGGGAGATG, designated herein as SEQ ID NO: 20; reverse sequence GCGTAGTTGACTGGCGAAGTT, designated herein as SEQ ID NO: 21; probe sequence AGGCCATCCGCACGGACAACCX, designated herein as SEQ ID NO: 22). Human DMPK RNA transcript levels were adjusted according to total RNA content, as measured by RIBOGREEN®. Results are presented as percent expression of human DMPK, relative to untreated control (UTC) cells. For example, if the UTC is 100 and a dose of 5000 nM of ISIS No. 445569 yields a % Expression of human DMPK of 35 then the 5000 nM dose of ISIS reduced expression of human DMPK by 65% relative to the UTC. The half maximal inhibitory concentration (IC₅₀) of each oligonucleotide is presented in the table below and was calculated by plotting the concentrations of oligonucleotides used versus the percent inhibition of human DMPK mRNA expression achieved at each concentration, and noting the concentration of oligonucleotide at which 50% inhibition of human DMPK mRNA expression was achieved compared to the control. The results are presented in Table 19.

The tested antisense oligonucleotide sequences demonstrated dose-dependent inhibition of human DMPK mRNA levels under the conditions specified above.

Example 13 In Vivo Antisense Inhibition of hDMPK in DMSXL Transgenic Mice

To test the effect of antisense inhibition for the treatment of myotonic dystrophy type 1 (DM1), an appropriate mouse model was required. The transgenic mouse model, DMSXL carrying the hDMPK gene with large expansions of over 1000 CTG repeats was generated (Huguet et al., PLOS Genetics, 2012, 8(11), e1003034-e1003043). These DMSXL mice express the mutant hDMPK allele and display muscle weakness phenotype similar to that seen in DM1 patients.

ISIS 486178 from Table 1 was selected and tested for antisense inhibition of hDMPK transcript in vivo. ISIS 445569 was included in the study for comparison.

Treatment

DMSXL mice were maintained on a 12-hour light/dark cycle and fed ad libitum normal Purina mouse chow Animals were acclimated for at least 7 days in the research facility before initiation of the experiment. Antisense oligonucleotides (ASOs) were prepared in PBS and sterilized by filtering through a 0.2 micron filter. ASOs were dissolved in 0.9% PBS for injection.

DMSXL mice received subcutaneous injections of ISIS 445569 at 50 mg/kg or ISIS 486178 at 25 mg/kg twice per week for 4 weeks. The control group received subcutaneous injections of PBS twice weekly for 4 weeks. Each treatment group consisted of 4 animals.

Inhibition of hDMPK mRNA Levels

Twenty four hours after the final dose, the mice were sacrificed and tissues were collected. mRNA was isolated for real-time PCR analysis of hDMPK and normalized to 18s RNA. Human primer probe set RTS3164 was used to measure mRNA levels. The results are expressed as the average percent of hDMPK mRNA levels for each treatment group, relative to PBS control.

Human primer probe set RTS3164 (forward sequence AGCCTGAGCCGGGAGATG, designated herein as SEQ ID NO: 20; reverse sequence GCGTAGTTGACTGGCGAAGTT, designated herein as SEQ ID NO: 21; probe sequence AGGCCATCCGCACGGACAACCX, designated herein as SEQ ID NO: 22).

As presented in Table 22 below, treatment with antisense oligonucleotides reduced hDMPK transcript expression. The results indicate that treatment with ISIS 445569 and 486178 resulted in reduction of hDMPK mRNA levels in DMSXL mice.

Example 14 Effect of ASO Treatment on Muscle Strength in DMSXL Mice Targeting hDMPK Griptest

Mice were assessed for grip strength performance in wild-type (WT) and DMSXL forelimb using a commercial grip strength dynamometer as described in the literature ((Huguet et al., PLOS Genetics, 2012, 801), e1003034-e1003043).

DMSXL mice received subcutaneous injections of ISIS 486178 at 25 mg/kg or ISIS 445569 at 50 mg/kg twice per week for 4 weeks. The control DMSXL group received subcutaneous injections of PBS twice weekly for 4 weeks. Each treatment group consisted of 4 animals. The forelimb force for each treatment group and WT was measured at day 0, 30, and 60 using the griptest. The grip strength performance was determined by measuring the force difference between day 60 and day 0. Results are presented as the average forelimb force from each group.

As illustrated in Table 23, below, treatment with ASOs targeting hDMPK improved muscle strength in DMSXL mice compared to untreated control. ISIS 486178, an ASO with cEt modifications, demonstrated substantial improvement in the forelimb strength (+3.4) compared to ISIS 445569 with MOE modifications (+0.38).

Example 15 Effect of ASO Treatment on Muscle Fiber Distribution in DMSXL Mice Targeting hDMPK

The muscle fiber distribution in DMSXL mice targeting hDMPK in the presence and absence of ISIS 445569 and 486178 was also assessed. Both ASOs were previously described in Table 1, above.

DMSXL mice received subcutaneous injections of ISIS 486178 at 25 mg/kg or ISIS 445569 at 50 mg/kg twice per week for 4 weeks. The control DMSXL group received subcutaneous injections of PBS twice weekly for 4 weeks. Each treatment group consisted of 4 animals. The muscle fiber distribution was assessed and the results are presented Table 44, below.

As illustrated, treatment with ASOs targeting hDMPK decreased the distribution of DM1 Associated Type 2c muscle fiber in the tibialis anterior (TA) of DMSXL mice compared to untreated control. The results demonstrated that normal pattern of fiber distribution in the skeletal muscles can be restored with ASO treatment. ISIS 445569 demonstrated an improvement in the muscle fiber distribution as compared to the untreated control; however ISIS 486178, an ASO with cEt modifications, demonstrated muscle fiber distribution that was more consistent with the muscle fiber distribution found in the wild-type mice.

Example 16 Dose-Dependent Antisense Inhibition of hDMPK in DMSXL Transgenic Mice

The newly designed ASOs from Table 1, above, were further evaluated in a dose-response study for antisense inhibition of hDMPK transcript in vivo. ISIS 445569 was included in the study for comparison.

Treatment

DMSXL mice were maintained on a 12-hour light/dark cycle and fed ad libitum normal Purina mouse chow Animals were acclimated for at least 7 days in the research facility before initiation of the experiment. Antisense oligonucleotides (ASOs) were prepared in PBS and sterilized by filtering through a 0.2 micron filter. ASOs were dissolved in 0.9% PBS for injection.

DMSXL mice received subcutaneous injections of PBS or ASOs from Table 1, above, targeting hDMPK. The ASO was dosed twice per week for 4 weeks at the indicated doses in Table 25, below. The control group received subcutaneous injections of PBS twice weekly for 4 weeks. Each treatment group consisted of 4 animals.

Inhibition of hDMPK mRNA Levels

Forty eight hours after the final dose, the mice were sacrificed and tissue from the tibialis anterior muscles, quadriceps muscles (left), gastrocnemius muscles, heart and diaphragm was isolated. mRNA was isolated for real-time PCR analysis of hDMPK and normalized to RIBOGREEN®. Human primer probe set RTS3164 was used to measure mRNA levels. The results summarized in Table 25, below, were independently generated from various dose-response studies. The results are presented as the average percent of hDMPK mRNA expression levels for each treatment group, relative to PBS control.

As presented, treatment with antisense oligonucleotides reduced hDMPK transcript expression in a dose-dependent manner.

Example 17 Six Week In Vivo Tolerability Study in CD-1 Mice

The newly designed ASOs from Table 1, above, were further evaluated in a 6 week study to assess plasma chemistry, body/organ weights and histology. Groups of CD-1 mice were administered 100 mg/kg/wk of ISIS 445569 or ISIS 512497. Further groups of CD-1 mice were administered 50 mg/kg/wk of ISIS 486178, ISIS 570808, ISIS 594292, ISIS 598768, ISIS 598769, ISIS 569473, ISIS 594300, and ISIS 598777. After six weeks and two days after each group of mice received the last dose, the mice were sacrificed and tissues were collected for analysis. For each group of mice, analysis to measure alanine transaminase levels, aspartate aminotransferase levels, blood urea nitrogen (BUN) levels, albumin levels, total bilirubin, and creatine levels was measured.
